Description Objects from the Class Slots Extends Methods Examples
Correlation or covariance structure for qualitative inputs (i.e. factors) obtained by nesting.
Objects can be created by calls of the form new("covQualNested",
...)
.
covLevels
:Object of class "function"
computing the covariance matrix
for the set of all levels.
covLevMat
:Object of class "matrix"
. The matrix returned by the
function in slot covLevels
. Since this matrix is often
needed, it can be stored rather than recomputed.
hasGrad
:Object of class "logical"
. If TRUE
, the analytical
gradient can be computed.
acceptLowerSQRT
:Object of class "logical"
. If TRUE
, the lower square
root of the matrix can be returned
label
:Object of class "character"
. A label to describe the
kernel.
d
:Object of class "integer"
. The number of inputs.
inputNames
:Object of class "character"
Names of the inputs.
nlevels
:Object of class "integer"
with length d
give the
number of levels for the factors.
levels
:Object of class "list"
with length d
. Gives the
levels for the inputs.
parLower
:Object of class "numeric"
. Lower bounds on the (hyper)
parameters.
parUpper
:Object of class "numeric"
. Upper bounds on the (hyper)
parameters.
par
:Object of class "numeric"
. Value of the (hyper) parameters.
parN
:Object of class "integer"
. Number of (hyper) parameters.
kernParNames
:Object of class "character"
. Name of the parameters.
group
:Object of class "integer"
. Group numbers: one for each final
level.
groupLevels
:Object of class "character"
. Vector of labels for the
groups.
between
:Object of class "covQual"
. A covariance or correlation
structure that can be used between groups.
within
:Object of class "list"
. A list of covariance or correlation
structures that are used within the groups. Each item has class
"covQual"
.
parNCum
:Object of class "integer"
. Cumulated number of
parameters. Used for technical computations.
contrasts
:Object of class "function"
. A contrast function like
contr.helmod
. This function must return a contrast matrix
with columns having unit norm.
Class "covQual"
, directly.
Class "covAll"
, by class "covQual", distance 2.
No methods defined with class "covQualNested" in the signature.
